Description

Die Erfindung betrifft ein Solarzellen-Montagemodul mit wenigstens einer Solarzelle bzw. wenigstens einem Solarzellenmodul sowie einem Blechprofil-Tragwerk sowie die Verwendung eines entsprechenden Bleches als Träger für Solarzellen bzw. Solarzellenmodule.The invention relates to a solar cell assembly module with at least a solar cell or at least one solar cell module as well as a sheet metal profile structure and the use of a corresponding sheet metal as a support for solar cells or solar cell modules.

Stand der TechnikState of the art

Aus der DE 198 28 462 A1 ist eine Dachabdichtung aus Dachbahnen zum Schutz eines Bauwerkes gegen Witterungseinflüsse bekannt, die einseitig Solarzellenmodule zur Engergiegewinnung aufweist. Die einzelnen Photovoltaik-Module sind jeweils wasserdicht und hochpolymer verkapselt und kraftschlüssig mit der Dachbahn verbunden.DE 198 28 462 A1 describes a roof sealing made of roofing membranes known for protecting a building against weather influences, which has one-sided solar cell modules for energy generation. The individual photovoltaic modules are each waterproof and encapsulated in high polymer and non-positively connected to the roofing membrane.

Ein wesentlicher Nachteil dieser Konstruktion ist es, daß die Solarzellenmodule nicht gegenüber der Sonne ausgerichtet werden können und damit der Wirkungsgrad der Module nicht optimal ist. Ein weiterer Nachteil dieser bekannten Technik ist es, daß sich die Module bei starker Sonneneinstrahlung stark aufheizen können, da rückseitig die Wärme nicht abgeführt werden kann. Die Aufheizung der Module wiederum führt zu vermindertem Wirkungsgrad und verringerter Lebensdauer.A major disadvantage of this construction is that the Solar cell modules cannot be aligned with the sun can and therefore the efficiency of the modules is not optimal. Another disadvantage of this known technique is that the modules can heat up strongly in strong sunlight, since the heat on the back cannot be dissipated. The Heating the modules in turn leads to reduced efficiency and reduced lifespan.

Aufgabetask

Aufgabe der vorliegenden Erfindung ist es daher, die Montage von Solarzellenmodulen zu vereinfachen und zu optimieren, ohne daß die o. gen. Nachteile dabei auftreten.The object of the present invention is therefore the assembly of solar cell modules to simplify and optimize without that the above-mentioned disadvantages occur.

Darstellung der ErfindungPresentation of the invention

Die Erfindung löst diese Aufgabe durch die Verwendung eines wenigstens einseitig mit einer Kunststoff-Folie einer Dicke von 0,25 bis 2 mm kaschierten Bleches als Träger für Solarzellen bzw. Solarzellenmodule. Bevorzugt wird als Kunststoff-Folie eine Dachdichtungsbahn eingesetzt. Besonders bevorzugt besteht die Kunststoff-Folie für die Kaschierung des Trägerbleches überwiegend aus einem Polymer, das aufgebaut ist aus den Monomeren Ethylen und wenigstens einem Comonomer, welches aus der Gruppe bestehend aus Vinylestern einer C2- bis C3- Alkancarbonsäure und C1- bis C4- Alkylestern der Acrylsäure ausgewählt ist.The invention solves this problem by using at least one on one side with a plastic film of a thickness of 0.25 to 2 mm laminated sheets as supports for solar cells or solar cell modules. A plastic film is preferred Roof sealing membrane used. There is particularly preferably the plastic film for the lamination of the carrier sheet predominantly from a polymer that is built up from the monomers Ethylene and at least one comonomer, which from the Group consisting of vinyl esters of a C2 to C3 alkane carboxylic acid and C1 to C4 alkyl esters of acrylic acid are selected is.

Folienbleche mit einer derartigen Kunststoff-Folie sind an sich bekannt und werden im Randbereich von Flachdächern verwendet.Foil sheets with such a plastic film are in themselves known and are used in the edge area of flat roofs.

Ein Solarzellen-Montagemodul gemäß der Erfindung besteht bevorzugt aus einem Blechprofil für das Tragwerk, das wenigstens einseitig mit einer Folie kaschiert ist. Die Solarzellen werden wiederum bevorzugt in eine Polymer-Folie eingeschweißt, wobei für die Vorder- und Rückseite ggf. unterschiedliche Polymere verwendet werden können, beispielsweise an der Oberseite eine besonders Schmutz- und wasserabweisende Folie auf Basis von Teflon-Material, während die Unterseite bevorzugt aus einem Polymer besteht, das verschweißbar ist mit der Folienbeschichtung des Blechprofil-Tragwerkes.A solar cell mounting module according to the invention is preferred from a sheet metal profile for the structure, which at least is laminated on one side with a film. The solar cells are again preferably welded into a polymer film, whereby Different polymers for the front and back if necessary can be used, for example on the top one especially dirt and water repellent film based on Teflon material, while the bottom is preferably made of a polymer exists, which is weldable with the film coating of the sheet profile structure.

Das Blechprofil-Tragwerk weist - im Querschnitt betrachtet - bevorzugt einen ersten nach außen weisenden Befestigungsschenkel, einen zweiten nach außen weisenden Befestigungsschenkel, einen etwa im Winkel von 90° bis 135° zu dem ersten Befestigungsschenkel verlaufenden Verbindungsschenkel und einem im Winkel von 110° bis 160° zum zweiten nach außen weisenden Befestigungsschenkel verlaufenden Tragschenkel auf. Auf diesen schräg verlaufenden Tragschenkel werden die Solarzellen bzw. Solarzellenmodule bevorzugt aufkaschiert. Ggf. können die die Solarzellen bzw. Solarzellenmodule auch mit dem Tragschenkel verklebt werden.The sheet profile structure has - viewed in cross section - preferably a first attachment leg pointing outwards, a second fastening leg pointing outwards, one approximately at an angle of 90 ° to 135 ° to the first Fastening leg extending connecting leg and one facing outwards at an angle of 110 ° to 160 ° to the second Fastening leg extending support leg. On this the solar cells or Solar cell modules preferably laminated on. Possibly. can they Solar cells or solar cell modules also with the support leg be glued.

Die Kaschierung der Solarzellen bzw. Solarzellenmodule erfolgt bevorzugt durch Warmgasschweißen, wobei es ausreicht, die Module im Randbereich mit dem folienkaschierten Blech-Tragwerk zu verbinden. Warmgasschweißen ist eine dem Durchschnittsfachmann geläufige Fügetechnik und eignet sich überraschenderweise auch zum Verbinden von Solarzellenmodulen, obgleich diese relativ temperaturempfindlich sind. Ggf. können die Solarzellenmodule jedoch auch beispielsweise mittels Lösungsmittel-Schweißung oder durch Klebung mit dem folienkaschierten Blech-Tragwerk verbunden werden.The solar cells or solar cell modules are laminated preferably by hot gas welding, whereby the modules are sufficient in the edge area with the foil-clad sheet metal structure connect. Hot gas welding is one of the average specialist common joining technology and surprisingly is also suitable for connecting solar cell modules, although these are relative are sensitive to temperature. Possibly. can the solar cell modules but also for example by means of solvent welding or connected to the foil-clad sheet metal structure by gluing become.

Es reicht aus, wenn die Polymer-Folie für die Kaschierung des Trägerbleches eine Dicke vom ca. 0,25 mm aufweist. Bevorzugt ist die Dicke max. 2 mm, da größere Dicken keine Vorteile mehr bewirken.It is sufficient if the polymer film for the lamination of the Carrier plate has a thickness of approximately 0.25 mm. Prefers is the thickness max. 2 mm, since greater thicknesses no longer have any advantages cause.

Die Folien-Kaschierung des Blechprofil-Tragwerkes ermöglicht nicht nur eine einfache Aufkaschierung der Solarzellenmodule, sondern insbesondere auch eine einfache und kostensparende Montage des Blechprofil-Tragwerkes auf beispielsweise Flachdächern.The foil lamination of the sheet metal profile structure enables not just a simple lamination of the solar cell modules, but also, in particular, simple and cost-saving installation of the sheet metal profile structure on, for example, flat roofs.

Es ist besonders vorteilhaft, wenn dieses mit einer Dachdichtungsbahn versehen ist, die wiederum mit der Folien-Kaschierung des Blechprofil-Tragwerkes verschweißt werden kann.It is particularly advantageous if this has a roof sealing membrane is provided, which in turn with the film lamination of the sheet metal profile structure can be welded.

Eine besonders bevorzugte Möglichkeit, ein solches Blechprofil-Tragwerk auf einem entsprechenden Flachdach zu befestigen, ist im folgenden beschrieben: das Blechprofil-Tragwerk mit den aufkaschierten Solarzellenmodulen wird zunächst in die gewünschte Himmelsrichtung ausgerichtet. Die Befestigung erfolgt durch Aufschweißen eines ca. 10 bis 20 cm breiten Streifens einer Dachdichtungsbahn insbesondere aus dem gleichen Material, wie es für die Kaschierung des Blechprofil-Tragwerkes und die Abdichtung des Flachdaches verwendet wird. Diese bevorzugt mit einer Verstärkungseinlage versehenen Dachbahn-Streifen werden je zur Hälfte ihrer Breite über die nach außen weisenden Tragschenkel des Blechprofil-Tragwerkes und die Dachbahn aufkaschiert, so daß die Kraftübertragung direkt über diese Dachbahn-Streifen erfolgt. Diese Montagemethode ist einerseits äußerst effektiv und andererseits völlig ausreichend in Bezug auf die notwendige Krafteinleitung von Windkräften etc. über die Dachdichtungsbahn in die Dachkonstruktion. Alternativ können die Blechprofil-Tragwerke auch mittels üblicher Schraubtechnik mit der Dachkonstruktion verbunden werden, wobei die Schrauben ggf. mittels aufkaschierter bzw. aufgeschweißter Lappen aus dem Dachdichtungs-Material abgedichtet werden können.A particularly preferred option, such a sheet profile structure to be attached to a corresponding flat roof described below: the sheet metal profile structure with the laminated Solar cell modules is first in the desired Orientation aligned. The attachment is made by Welding on a strip about 10 to 20 cm wide Roof waterproofing membrane in particular made of the same material as it for the lamination of the sheet metal profile structure and the sealing of the flat roof is used. This preferred with a reinforcement insert provided roofing strips each half their width over the outward-pointing support legs of the sheet profile structure and the roofing membrane laminated, so that the power transmission directly over this roofing strip he follows. On the one hand, this method of assembly is extreme effective and, on the other hand, completely sufficient in terms of the necessary force transmission of wind forces etc. via the Roof sealing membrane in the roof structure. Alternatively, you can the sheet profile structures also using conventional screw technology to be connected to the roof structure using the screws if necessary, by means of laminated or welded rags from the Roof sealing material can be sealed.
